What Makes WordPress Website So Slow?

The problem of WordPress website speed is a problem encountered by many people. But what caused the website to be so slow? It is a problem that many people cannot solve. Some people even gave up WordPress, the world’s most popular website system. The following points are combined with years of research to analyze the reasons for the slow establishment of the WP theme. To provide WordPress website performance, first, understand the factors that cause the WordPress website to be slow.

The main factors that cause a WordPress website to be slow:

Website Hosting

A host running a WordPress website should at least meet the requirements recommended by WordPress in order to achieve the desired website speed.

To run WordPress, make use of host with the following hosting support:

PHP version 7 or higher
MySQL 5.6 or more advanced version or MariaDB 10.0 or more sophisticated version
HTTPS support

Whether it is Apache or Nginx, it is recommended to support rewriting modules. This is not to say that this is necessary support, but the host must support PHP 5.2.4+ and MySQL 5.0+.

Why it is better to meet the recommended configuration:

PHP7 is a big improvement over the previous version. So, to run WordPress it is best to use PHP7. If this version cannot be met, PHP 5.4 or higher is strongly recommended to avoid an potential slow speed of a website loading. Now WordPress database supports utf8mb4 encoding, Mysql5.6 + support for this encoding is more perfect.

WordPress configuration

Here mainly talk about website caching issues. Because every page of WordPress needs to be queried from the database, if streak directly, it will increase the burden on the host. So, install a cache plugin. Cache to CDN when necessary.

Page size

This is mainly because the images are not well optimized for the web. Some companies directly upload photos taken on the Internet, which is not a good practice.
